ABSTRACT:
A base station for a time division duplex (TDD) cordless telephone system has a frequency division duplex (FDD) transmit signal path for outputting FDD transmit signals, the transmit signal path including a transmit signal timing generator for controlling the timing of the transmit signals, and an FDD receive signal path for processing FDD receive signals input into the base station. The receive signal path includes a demodulator for demodulating the receive signals, a bit timer responsive to bit clock timing in the receive signals for controlling the timing of the receive signals in dependance on the receive signal bit clock timing and a data processor responsive to the demodulator and the bit timer for correspondingly varying the timing of the receive signals.
